PURPOSE: To reduce the loss of pressure, by packing a gas-liquid part with long reticulated tubes and arranging said tubes so as to direct the axial direction thereof toward a gas-liquid counterflow direction.
CONSTITUTION: Gas to be treated is injected into a vertical type gas-liquid contact tower 1 from the gas introducing port 2 formed to the lower side wall surface of said contact tower 1. The injected gas is distributed below a gas-liquid contact part 3 and enters the gas-liquid contact part 3 as a uniform stream. The gas-liquid contact part 3 is packed with long reticulated tubes 9 and an absorbing solution is fallen from spray nozzles 4 and, at the same time, gas is introduced from below to allow respective long reticulated tubes 9 to function wetted walls. By this mechanism, the gas can rise through cavity parts of the long reticulated tubes 9 in a counterflow state to obtain highly efficient gas- liquid contact.
